From such topics as extraterrestrial life to comets on a collision course with Earth, this program explores the current state of our understanding of the cosmos. The participants in this wide-ranging discussion include Feryal Ozel, a specialist on the subjects of neutron stars and black holes; John Bahcall, a pioneer in neutrino astrophysics and the driving force behind the construction of the Hubble Space Telescope; Sara Seagar, a rising star in planetary system research who studies large extra-solar planets; and Freeman Dyson, an elder statesman of the scientific community whose ideas are so original that his colleagues coined the term "Dysonian" to describe any highly imaginative idea.

In this compelling series filmed at Princeton's renowned Institute of Advanced Study, National Public Radio's Ira Flatow introduces viewers to some of today's greatest minds through intimate, cross-disciplinary conversations that spotlight science, mathematics, history, linguistics, art, and music. Each program probes the frontiers of knowledge as Institute faculty members and visiting scholars share their theories, insights, and passions.
